DETAILED DESCRIPTION

FIG. 1A illustrates a perspective view of a semiconductor package device 1 in accordance with some embodiments of the present disclosure. The semiconductor package device 1 includes a substrate 10, an antenna 11, a conductor 12 and an electronic component 13.

The substrate 10 may include, for example, a printed circuit board, such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass-fiber-based copper foil laminate. The substrate 10 may include an interconnection structure (or electrical connection), such as a redistribution layer (RDL) or a grounding element. The substrate has a surface 101 and a surface 102 opposite to the surface 101. In some embodiments, the surface 101 of the substrate 10 is referred to as an upper surface or a first surface and the surface 102 of the substrate 10 is referred to as a lower surface or a second surface. In some embodiments, the substrate 10 may include multiple layers (e.g., metal layers), and the layers can be electrically connected through one or more interconnection structures 10 v (e.g., vias). In some embodiments, the substrate 10 includes a ground layer 10 g disposed between the surface 101 of the substrate 10 and the surface 102 of the substrate 10. In some embodiments, the surface 101 of the substrate 10 and the ground layer 10 g of the substrate 10 are electrically connected through one or more of the interconnection structures 10 v. In some embodiments, one or more of the interconnection structures 10 v extend from the surface 101 of the substrate 10 to at least the ground layer 10 g. In some embodiments, the substrate 10 may include electrical contacts 10 b (e.g., solder bumps) on the surface 102 to provide electrical connections between the semiconductor package device 1 and other circuits or electrical devices.

The antenna 11 is disposed on the surface 101 of the substrate 10. In some embodiments, the antenna 11 includes a single antenna element. In some embodiments, the antenna 11 may include multiple antenna elements. For example, the antenna 11 may include an array including a patch antenna, a dipole antenna, a monopole antenna or the like. In some embodiments, the antenna 11 may include an M×N array of antenna elements, where M or N is an integer greater than 1. In some embodiments, M can be the same as or different from N depending on design specifications. For example, the antenna 11 may include a 4×4 array of antenna elements. For example, the antenna 11 may include a 4×1 array of antenna elements.

The conductor 12 is disposed on the surface 101 of the substrate 10. The conductor 12 may be referred to herein as a “conductive frame.” The conductor 12 is adjacent to and disposed around the antenna 11. For example, the conductor 12 surrounds the antenna 11. For example, the conductor 12 is disposed at the periphery of the antenna 11. For example, the conductor 12 includes four sheets 12 a, 12 b, 12 c and 12 d, disposed at respective edges of the antenna 11. In some embodiments, there is gap between one or more pairs of adjacent sheets of the conductor 12. For example, there are respective gaps between the sheets 12 a and 12 b, the sheets 12 b and 12 d, the sheets 12 d and 12 c or the sheets 12 c and 12 a. In some embodiments, the gaps are located adjacent to respective corners of the antenna 11. In some embodiments, the conductor 12 includes one or more metals, metal alloys, or other conductive materials.

As shown in FIG. 1B, which illustrates a cross-sectional view of the semiconductor package device 1 along the y-direction in FIG. 1A, each sheet of the conductor 12 has a surface 121 (also referred to as first surface) facing toward the antenna 11 (e.g. a surface 121 on an antenna side of the sheet of the conductor 12, which need not directly face the antenna 11) and a surface 122 (also referred to as second surface) opposite to the surface 121. In some embodiments, there is a distance between the surface 121 and the surface 122. For example, the sheet of the conductor 12 has a thickness. The surface 122 faces toward the surface 101 of the substrate 10, directly or indirectly, and is spaced apart from the surface 101 of the substrate 10. In some embodiments, the surface 121 of each sheet of the conductor 12 includes an electromagnetic-reflective surface. For example, the surface 121 can reflect one or more electromagnetic waves radiated by the antenna 11, so as to direct the electromagnetic waves in a predetermined direction (e.g., in the z-direction shown in FIG. 1A), which can increase the radiation efficiency (or the gain) of the antenna 11. In some embodiments, the surface 122 of each sheet of the conductor 12 includes a thermal dissipation surface, so as to increase the heat dissipation of the semiconductor package device 1. In some embodiments, a roughness of the surface 121 is different from a roughness of the surface 122. For example, the roughness of the surface 121 is less than the roughness of the surface 122 (e.g. the roughness of the surface 121 is about 0.9 or less, about 0.8 or less, or about 0.7 or less times the roughness of the surface 122). In some embodiments, as shown in FIG. 1B, an angle θ1 defined by the surface 101 of the substrate 10 and the surface 122 of the conductor 12 is greater than 0 degrees and is less than or equal to about 90 degrees, such as greater than 0 degrees and less than or equal to about 80 degrees.

In some embodiments, the conductor 12 is spaced apart from the surface 101 of the substrate 10 (e.g. does not directly contact the surface 101 of the substrate 10). The conductor 12 may include a first terminal that is adjacent to the surface 101 of the substrate 10, and a second terminal opposite to the first terminal. The first terminal may be electrically connected to an interconnection structure 10 v, and/or may be electrically connected to a grounding element disposed in the substrate 10 that is exposed by the surface 101. There may be a distance between the surface 101 of the substrate 10 and the first terminal of the conductor 12 that is adjacent to the surface 101 of the substrate 10. For example, as shown in FIG. 1B, a connection member 12 s (e.g., a soldering layer or an electrically conductive adhesive layer) is disposed between the conductor 12 and the surface 101 of the substrate 10. The connection member 12 s connects the first terminal of the conductor 12 that is adjacent to the surface 101 of the substrate 10 to the substrate 10.

The electronic component 13 is disposed on the surface 102 of the substrate 10. In some embodiments, the electronic component 13 is electrically connected to the antenna 11 through the interconnection structure 10 v (which can function as a feeding element) within the substrate 10. The electronic component 13 may include a chip or a die including a semiconductor substrate, one or more integrated circuit devices and one or more overlying interconnection structures therein. The integrated circuit devices may include active devices such as transistors and/or passive devices such resistors, capacitors, inductors, or a combination thereof. The electronic component 13 may be electrically connected to the substrate 10 (e.g., to conductive pads of the substrate 10 or disposed on the substrate 10), and electrical connection may be attained by way of flip-chip or wire-bond techniques.

FIG. 2A illustrates a perspective view of a semiconductor package device 2 in accordance with some embodiments of the present disclosure. The semiconductor package device 2 is similar to the semiconductor package device 1 in FIG. 1A, and one of the differences therebetween is that the conductor 12 of the semiconductor package device 1 includes four sheets 12 a, 12 b, 12 c and 12 d while a conductor 22 of the semiconductor package device 2 includes four triangular prisms 22 a, 22 b, 22 c and 22 d. Although the electronic component 13 and the electrical contacts 10 b as shown in FIG. 1A are not illustrated in FIG. 2A, the electronic component 13 and the electrical contacts 10 b can be added to the semiconductor package device 2 (e.g., on the surface 102 of the substrate 10) according to design specifications.

The conductor 22 is disposed on the surface 101 of the substrate 10. The conductor 22 is adjacent to and disposed around the antenna 11. For example, the conductor 22 surrounds the antenna 11. For example, the conductor 22 is disposed at the periphery of the antenna 11. For example, the conductor 12 includes the four triangular prisms 22 a, 22 b, 22 c and 22 d, disposed at respective edges of the antenna 11. In some embodiments, there is gap between each two adjacent triangular prisms of the conductor 22. For example, there is a gap between the triangular prisms 22 a and 22 b, the triangular prisms 22 b and 22 d, the triangular prisms 22 d and 22 c or the triangular prisms 22 c and 22 a. In some embodiments, the gaps are located adjacent to respective corners of the antenna 11.

As shown in FIG. 2B, which illustrates a cross-sectional view of the semiconductor package device 2 along the y-direction in FIG. 2A, each triangular prism of the conductor 22 has a surface 221 (also referred to as first surface) facing toward the antenna 11 (e.g. a surface 221 on an antenna side of the sheet of the conductor 22, which need not directly face the antenna 11), a surface 222 (also referred to as second surface) adjacent to the surface 221 and a surface 223 adjacent to the surface 221 and to the surface 222. In some embodiments, the surface 222 is substantially perpendicular to the surface 101 of the substrate 10. In some embodiments, the surface 223 is substantially parallel to the surface 101 of the substrate 10 and, for example, spaced apart from the surface 101 of the substrate 10 by a connection element 22 s (e.g., a soldering layer including solder material, or an electrically conductive adhesive layer). In some embodiments, the surface 221 of the conductor 22 includes an electromagnetic-reflective surface. For example, the surface 221 can reflect one or more electromagnetic waves radiated by the antenna 11, so as to direct the electromagnetic waves in a predetermined direction (e.g., in the z-direction shown in FIG. 2A), which can increase the radiation efficiency (or the gain) of the antenna 11. In some embodiments, the surface 222 of the conductor 22 includes a thermal dissipation surface, so as to increase the heat dissipation of the semiconductor package device 2. In some embodiments, a roughness of the surface 221 is different from a roughness of the surface 222. For example, the roughness of the surface 221 is less than the roughness of the surface 222 (e.g. the roughness of the surface 221 is about 0.9 or less, about 0.8 or less, or about 0.7 or less times the roughness of the surface 222). In some embodiments, an angle defined by the surface 101 and the surface 221 can be less than 180 degrees and greater than or equal to about 90 degrees, such as less than 180 degrees and greater than or equal to about 100 degrees.

In some embodiments, as shown in FIG. 2C, the semiconductor package device 2 may further include a package body 29 on the surface 101 of the substrate 10 and covering the antenna 11 and at least a portion of the conductor 22. In some embodiments, a top portion of the conductor 22 is exposed from the package body 29. In some embodiments, as shown in FIG. 2D, a package body 29′ may selectively cover a portion of the conductor 22 and may expose a top portion of the conductor 22, the surface 221 of the conductor 22, and the antenna 11. In some embodiments, the package body 29 or 29′ includes an epoxy resin having fillers dispersed therein.

FIG. 3 illustrates a perspective view of a semiconductor package device 3 in accordance with some embodiments of the present disclosure. The semiconductor package device 3 is similar to the semiconductor package device 1 in FIG. 1A, and one of the differences therebetween is that the conductor 12 of the semiconductor package device 1 includes four sheets 12 a, 12 b, 12 c and 12 d, while a conductor 32 (including four sheets 32 a, 32 b, 32 c and 32 d) of the semiconductor package device 3 further includes a plurality of fin structures 32 f adjacent to the surface 101 of the substrate 10 and the surface 122 of the conductor 12 as shown in FIG. 1A. The fin structures 32 f are disposed on the surface 101 of the substrate 10 and connected to the surface 122 of the conductor 12 as shown in FIG. 1A. Compared with the conductor 12 in FIG. 1A, the fin structures 32 f of the conductor 32 may further improve the heat dissipation of the semiconductor package device 3. Although the electronic component 13 and the electrical contacts 10 b as shown in FIG. 1A are not illustrated in FIG. 3, the electronic component 13 and the electrical contacts 10 b can be added to the semiconductor package device 3 (e.g., on the surface 102 of the substrate 10) according to design specifications.

FIG. 4A illustrates a cross-sectional view of a semiconductor package device 4 in accordance with some embodiments of the present disclosure. The semiconductor package device 4 is similar to the semiconductor package device 1 in FIG. 1A, and one of the differences therebetween is that in FIG. 1A, the electronic component 13 is disposed on the surface 102 of the substrate 10 while in FIG. 4, the electronic component 13 is disposed on the surface 101 of the substrate 10. The electronic component 13 is disposed adjacent to the antenna, which is disposed on the surface 101 of the substrate 10 and surrounded by a conductor 42. The electronic component 13 is separated from the antenna 11 by the conductor 42 (e.g. the conductor 42 is disposed between the electronic component 13 and the antenna 11). The electronic component 13 is electrically connected to the electronic component 13 through a feeding line 10 f within the substrate 10. In some embodiments, the conductor 42 can be the same as any of the conductor 12 in FIG. 1A, the conductor 22 in FIG. 2A and the conductor 32 in FIG. 3.

FIG. 4B illustrates a perspective view of a portion of the semiconductor package device 4 circled by a dotted-line square 4A shown in FIG. 4A in accordance with some embodiments of the present disclosure. The feeding line 10 f is extended within the substrate 10 and connects the antenna 11 to the electronic component 13 as shown in FIG. 4B. In some embodiments, the interconnection structures 10 v include a plurality of vias, and the feeding line 10 f can connect the antenna 11 to the electronic component 13 through a gap between vias of the plurality of vias. In some embodiments, as shown in FIG. 4C, one or more interconnection structures 10 v′ may include a plurality of metal plates (e.g., which can function as compartment shielding) within the substrate 10. At least one of the metal plates defines an aperture 10 h, so that the feeding line 10 f can connect the antenna 11 to the electronic component 13 through the aperture 10 h.

Referring to FIG. 5B, a conductor 12 is disposed on the surface 101 of the substrate 10 to surround the antenna 11. For example, the conductor 12 is disposed at the periphery of the antenna 11. In some embodiments, the conductor 12 is connected to the ground element exposed from the surface 101 of the substrate 10 by a connection member 12 s (e.g., including a soldering material). In some embodiments, in the operation of FIG. 5B, the conductor 12 can be replaced by any of the conductors 22 and 32 as shown in FIG. 2B and FIG. 3.

Referring to FIG. 5C, an electronic component 10 b and an electronic component 13 are provided (e.g. formed or disposed) on the surface 102 of the substrate 10 to form the semiconductor package device 1 in FIG. 1B. In some embodiments, the electronic component 13 can be formed on the surface 101 of the substrate 10 to form the semiconductor package device 4 in FIG. 4A. For example, the electronic component 13 can be formed adjacent to the antenna and separated from the antenna by the conductor.

As used herein, the terms “approximately,” “substantially,” “substantial” and “about” are used to describe and account for small variations. When used in conjunction with an event or circumstance, the terms can refer to instances in which the event or circumstance occurs precisely as well as instances in which the event or circumstance occurs to a close approximation. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation less than or equal to ±10% of that numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, two numerical values can be deemed to be “substantially” the same if a difference between the values is less than or equal to ±10% of an average of the values, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, “substantially” parallel can refer to a range of angular variation relative to 0° that is less than or equal to ±10°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, “substantially” perpendicular can refer to a range of angular variation relative to 90° that is less than or equal to ±10°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

Two surfaces can be deemed to be coplanar or substantially coplanar if a displacement between the two surfaces is no greater than 5 μm, no greater than 2 μm, no greater than 1 μm, or no greater than 0.5 μm.

Additionally, amounts, ratios, and other numerical values are sometimes presented herein in a range format. Such range formats are used for convenience and brevity, and should be understood flexibly to include not only numerical values explicitly specified as limits of a range, but also all individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly specified.

As used herein, the terms “conductive,” “electrically conductive” and “electrical conductivity” refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m). Typically, an electrically conductive material is one having a conductivity greater than approximately 10⁴ S/m, such as at least 10⁵ S/m or at least 10⁶ S/m. The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

In the description of some embodiments, a component provided “on” or “over” another component can encompass cases where the former component is directly on (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component.
